Certain 900-MHz baby monitor systems cause interference to Z-Wave systems. If the system is a 900-MHz system, it usually has a channel selector on the camera and the monitor. For two-channel systems, move each selector to Channel B. For three-channel systems, move each selector to Channel C. You may continue to use your baby monitor as a separate system, but you will not be able to view the baby monitor transmission through your ADT Pulse portal.
